My cooling squirrel cage fan gearbox had been completely redone before I bought the bus but for whatever reason it is pouring oil out in just a couple of hours of driving. I'm in serious need of a shop that can R&R this for me somewhere in the Gatlinburg TN or Gettysburg PA or somewhere in between areas. Can someone suggest a shop? I'm now on a tour so every weekend I have to be somewhere else and this is the only bummer I'm currently facing with our coach which has been otherwise perfect. Anyway I can temporarily stem the bleeding so I can get to a shop without seizing up my gearbox?

This will probably be out of the way for you, but you could give Davids Coach Service a try .12 miles south of Morganton N C on hiway 18. P/N 8288746105
Scott, how about choo choo in Chatanooga? Joel is currently inspecting our Eagle and replacing the air compressor and installing a drier which was missing.
It was amazing watching Joel remove the Air Compressor as you could tell he was an expert and had done it many many times before.
All th best.
Chop chop is in Chattanooga??! I was just there for a week. I guess I didn't know they were there. Boo. Ok. I might give them a ring. David's coach might be an idea on our way down to florida but I'm trying to get this done sooner than later. Can I use a thicker gear type
Lube to slow the bleeding temporarily?

Choo-Choo is just south of Chattanooga in Rossville, Georgia.
Scott, I am not familiar with that gearbox at all, but the leak has to be a seal, gasket, crack, missing bolt or loose drain plug. Clean the area and check it with a strong light wherever you can. Injecting grease might buy you time, but that is a gamble. Knoxville is probably your closest service area, but you need someone who knows MCI's. It might be a simple fix if you can find the trouble spot.
If you can find a Gray Line shop they will work on it ? is blowing from the breather or leaking on 1 of the 3 shafts,I sure hope it's simple and doesn't need to come out what a pain to remove `
Mine was leaking after i got it and i found the the bolts on top were loose.
Scott 1st you need to make sure that it hasn't been overfilled! Second like Clifford say's it's a major pain to R&R however if it was really redone just before you bought it, things could be somewhat easier.
We rebuilt one of ours shortly before we lost the engine to a turbo failure. And if memory serves me correctly we used screws or bolts to put the fan housings back on instead of all those pesky buck rivets that were in it originally!
So if someone put it back in w/bolts or screws R&R will be MUCH easier.
Also Premier Coach in Knoxville has a good shop and good people to work with!
Mike the general manager is a super great guy and very helpful!
Or I know a guy over in NC that used to be the shop foreman for Setra before they merged w/MCI and moved to Louisville that does great work! (but I also suggest David's Coach in NC as he keeps Huggy going for Ned Sanders!)
BTW if your interested I do have the unit we rebuilt still in the "parts bus" sitting here at the shop. How long are you in Gatlinburg?
Cliff, that's the thing, this box has less than 2,000 miles on it since the complete pull out and RR. New rubber bushings and everything. It didn't leak a drop not a single drop driving from Texas to Michigan. Now all the sudden it's spraying all over the compartment and engine. Seems like a fine mist. It doesn't leak a drop when sitting. Did I overfill it? I filled it till the sight glass was full and actually had a small amount of oil spill over out the fill tube before putting the plug cap back in. If I overfilled it could
That cause it to be emptying itself? I can't find the breather/vent. I'm trying to find that to see if it's plugged.

Scott been a LONG time since I fooled with one, but yes it sounds like you overfilled it. If I remember correctly the sight glass is pretty low on the case. In no way should it have been spilling out the top if you put it 1/2 to 3/4 way up in the sight glass! (btw it doesn't hold much)
BTW IIRC the breather vent should be right on top kinda a mushroom looking cap type thing.
It sounds like B_K may have you on the right track but if you need further assistance close by, East Tennessee Luxury Coach is near Vonore about an hour or so west of you. Jeff Rowe works mostly on Prevost but he is an excellent mechanic and an even better guy. I highly recommend him.

Davy
Looks like you need to siphon some oil out until the level is visible at the top of the sight glass.
Don't fill it more than 1/2 way up the glass. It will expand as it warms up and there's not much room for expansion. Sounds like it just expanded and pushed the excess out the top because it was over filled.

Scott If you do not get it straighten out David will be great. While there you can check on HUGGY for me.
Also check on several newer 45 ft, "PREVOS" that he is servicing also.
if you are coming from Ashville way Gene Russells might be closer.
And he is something,just ask Boomer.

1/2 way up the glass (or less) checked hot.
Ok thank you so much. I'm going to try to get it at the right level tomorrow and see how it does. It didn't leak a drop until this past week after I topped it off. Now it empties itself. I still don't see a vent. Will take pics

If the gear box is simliar to a 9/12 it should be right on the top plate (https://busconversionmagazine.com/forum/proxy.php?request=http%3A%2F%2Fi1265.photobucket.com%2Falbums%2Fjj520%2Fkrank57%2F20150827_134816_zpshw8glsdd.jpg&hash=2edc82b4061ec7956c03af6f0efd537e35cdc3eb) (http://s1265.photobucket.com/user/krank57/media/20150827_134816_zpshw8glsdd.jpg.html)
You guys rock. Those two photos were exactly what I needed. You beat me to it. I found mine and sure enough that's where all the oil is spraying out in a nice fine mist. It's literally coated everything in my engine bay with nice clean brand new 40wt. I just simple greened it a month ago too. Oh well. So my problem is solved: this morning my sightglass was empty. I attempted to add more oil, and that oil came out the top of the fill tube. So evidently it was completely full still. I wiggled the hose going to the sight glass, and immediately the sight glass filled completely to the top. So apparently I have a kink in my sight glass tube somewhere and it is not always registering when the box is full. In other words I have not leaked a drop of oil out of any of the seals, I have only been spraying out of the vent because I have overfilled it because the sight glass was not registering. Note to self wiggle sight glass hoses before filling your box. thank you so much for your help guys this was an easy issue.

Glad it was solved. I wish that all of the problems were so easy and so cheap.
